Answer to Question 1

Answer: Earth has plate tectonics. Mars does not. Shield volcanoes that erupted due to hot-spot activity on Earth got carried away from their hot-spot magma source due to the motion of the plate on which they erupted. On Mars, no such lateral motion exists, so the lava keeps piling up for the duration of the hot spot's activity.

Answer to Question 2
